What is the difference between a 504 plan and an IEP?

A 504 plan is based on Section 504 of the Rehabilitation Act, a civil rights law that prohibits disability discrimination. It provides accommodations that ensure equal access to education but does not include specialized instruction or modified curriculum. An Individualized Education Program (IEP) is based on the Individuals with Disabilities Education Act (IDEA), which provides specially designed instruction and related services for students who meet specific disability categories. An IEP requires a more extensive evaluation process and provides more comprehensive services. A child with ADHD who needs extended test time and preferential seating may qualify for a 504 plan, while a child with ADHD who also needs specialized reading instruction may need an IEP.

Does my letter guarantee the school will provide the accommodations I recommend?

No. The school district makes the final determination about whether the student qualifies under Section 504 and what accommodations are appropriate. Your letter provides the clinical evidence that supports the request, but the school's 504 team — which includes the parent, teachers, and school staff — makes the decision. However, a well-documented letter from a qualified clinician carries significant weight in this process, and the school is required to consider the information you provide.

What qualifies as a disability under Section 504?

Section 504 uses a broad definition of disability: a physical or mental impairment that substantially limits one or more major life activities. For students, the most relevant major life activity is learning, but others include concentrating, thinking, reading, communicating, and social interaction. The standard is 'substantially limits' — the impairment does not need to be severe, but it must be more than minor or trivial. Importantly, the determination is made without considering the ameliorative effects of medication, so a child whose ADHD symptoms are partially controlled by medication may still qualify if the underlying condition substantially limits learning.

Can I write a 504 accommodation letter without conducting a full psychological evaluation?

Yes, depending on your role and the nature of the condition. If you are the treating therapist or psychiatrist who has diagnosed and treated the child, your clinical documentation can support a 504 request. However, some school districts prefer or require a formal psychoeducational evaluation. For conditions like ADHD, anxiety, or depression where the diagnosis has been established through clinical assessment and the functional limitations are well-documented in your treatment records, a detailed letter from the treating clinician is generally sufficient. For learning disabilities or intellectual disabilities, a formal evaluation is typically required.

Should I recommend specific accommodations or just describe the functional limitations?

Both. Describe the functional limitations in detail so the 504 team understands the clinical basis for the accommodations, and then recommend specific accommodations that address those limitations. Your recommendations should be evidence-based and connected logically to the limitations you have described. The 504 team may implement your exact recommendations, modify them, or substitute alternatives, but your clinical perspective on what accommodations would be effective is an important part of the team's decision-making process.

School Accommodation Letter from Psychologist (504 Plan Support)

What Is a School Accommodation Letter?

A school accommodation letter is a clinical document written by a psychologist, psychiatrist, or other qualified mental health professional to support a student's request for accommodations under Section 504 of the Rehabilitation Act of 1973. Section 504 is a federal civil rights law that prohibits discrimination against individuals with disabilities in programs receiving federal funding, including public schools.

Under Section 504, a student with a disability that substantially limits one or more major life activities — including learning, concentrating, reading, thinking, and communicating — is entitled to accommodations that provide equal access to education. The school develops a 504 plan that specifies the accommodations the student will receive. Common accommodations include extended time on tests, preferential seating, modified homework assignments, movement breaks, and access to a quiet testing environment.

Your letter provides the clinical foundation for the 504 plan. It documents the student's diagnosis, describes the functional limitations in the educational setting, and recommends specific accommodations that address those limitations. A strong letter translates clinical information into educational terms that teachers and administrators can understand and implement.

This letter differs from a special education referral in that Section 504 provides accommodations for equal access, not specialized instruction. If the student needs a modified curriculum or specialized teaching methods, they may need an evaluation for an Individualized Education Program (IEP) under the Individuals with Disabilities Education Act (IDEA) instead.

When You Need It

When a parent is requesting a 504 plan for a child with a diagnosed mental health condition
When a school requests clinical documentation to evaluate a 504 eligibility request
When a student's existing 504 plan needs to be updated or renewed with current clinical information
When a student with ADHD, anxiety, depression, or another mental health condition is struggling academically and needs formal accommodations
When a student is transitioning to a new school and needs documentation to transfer their 504 plan

Key Components

Your credentials and relationship to the student. State your name, license type, license number, and your role in the student's care. Specify whether you conducted a formal evaluation, are the treating therapist, or are the prescribing psychiatrist. Include how long you have been working with the student.

Diagnosis with relevant codes. Provide the student's diagnosis with ICD-10-CM codes. If the diagnosis was established through formal testing (such as a psychoeducational evaluation or neuropsychological assessment), reference the assessment and its date.

Functional limitations in the educational setting. This is the most important section. Describe how the student's condition specifically affects their ability to learn, concentrate, complete work, interact with peers, and function in the classroom. Use concrete, behavioral language that teachers can recognize. Avoid clinical jargon — describe what the teacher would observe, not how the condition would be categorized in a clinical manual.

Assessment data. Include scores from standardized measures, rating scales (such as the Conners, BASC-3, or Vanderbilt), and any formal testing results. If parent and teacher rating scales were administered, include both perspectives.

Recommended accommodations. List specific accommodations and connect each one to the functional limitation it addresses. Accommodations should be evidence-based and practical for classroom implementation.

504 Plan Support Letter — ADHD Classroom Accommodations

504 Coordinator Westfield Elementary School 1850 Parkwood Avenue Charlotte, NC 28205

Re: 504 Accommodation Request for Ethan M. Nguyen, Grade 4

Dear 504 Team,

I am writing to support a Section 504 accommodation request for Ethan M. Nguyen, a fourth-grade student at Westfield Elementary. I am a licensed clinical psychologist (NC License #6192) specializing in child and adolescent neuropsychological assessment. I conducted a comprehensive evaluation of Ethan on January 15-16, 2026, and I have been providing follow-up consultation with his family since that time.

Diagnosis:

Attention-Deficit/Hyperactivity Disorder, Combined Presentation (F90.2)
Specific Learning Disorder with impairment in written expression (F81.81)

Evaluation Summary: Ethan was referred for evaluation due to increasing academic difficulties, particularly with sustained attention, task completion, and written assignments. I administered the WISC-V, WIAT-4, Conners-4 (parent and teacher forms), BRIEF-2 (parent and teacher forms), CPT-3, and a clinical interview with Ethan and his parents.

Ethan's cognitive abilities fall in the average to above-average range (WISC-V FSIQ: 108). However, his processing speed (PSI: 88) and working memory (WMI: 91) are significantly lower than his verbal comprehension (VCI: 118) and visual-spatial reasoning (VSI: 112), creating a pattern consistent with ADHD-related processing inefficiencies. His CPT-3 results showed significant elevations in omission errors (T=72) and hit reaction time variability (T=68), consistent with sustained attention difficulties.

On the Conners-4, both parent and teacher ratings placed Ethan in the clinically significant range for inattention (parent T=74, teacher T=71) and the elevated range for hyperactivity/impulsivity (parent T=67, teacher T=64). BRIEF-2 ratings showed clinically significant elevations in working memory (parent T=73, teacher T=70), plan/organize (parent T=69, teacher T=72), and task monitor (parent T=71, teacher T=68).

Written expression on the WIAT-4 fell in the below-average range (standard score: 82), with particular difficulty in sentence composition and organizational structure, despite average to above-average oral language abilities.

Functional Limitations in the Classroom:

Sustained attention: Ethan's teacher reports that he is unable to sustain focus on independent work for more than 8 to 10 minutes without redirection. During whole-group instruction, he frequently loses track of the lesson and misses key information, particularly during transitions between topics. His CPT-3 results confirm a significant deficit in sustained attention.

Task completion: Ethan consistently fails to complete in-class assignments within the allotted time. His teacher reports that he completes approximately 50-60% of assigned work during class, despite demonstrating understanding of the material when assessed verbally. This is consistent with his processing speed weaknesses and his difficulty maintaining task engagement.

Written output: Ethan's written work is significantly below the level expected given his verbal abilities. He produces brief, disorganized written responses and frequently omits required components of assignments. Writing tasks that require sustained effort and organization are the most problematic. This reflects both his ADHD-related executive function weaknesses and his specific learning disorder in written expression.

Organization and planning: Ethan frequently loses materials, forgets to turn in completed assignments, and has difficulty breaking multi-step projects into manageable components. His parents report spending two to three hours nightly on homework that his teacher estimates should take 45 minutes.

Self-regulation in the classroom: Ethan fidgets, leaves his seat, and seeks movement throughout the school day. While he is not disruptive to other students, his motor restlessness interferes with his own learning and task engagement.

Recommended Accommodations:

Based on the evaluation findings and Ethan's functional limitations, I recommend the following Section 504 accommodations:

Extended time on tests and assignments (1.5x standard time) — to address processing speed weaknesses and allow Ethan to demonstrate his knowledge without the penalty of slow output speed.
Preferential seating near the teacher and away from high-traffic areas and windows — to reduce environmental distractions and facilitate teacher monitoring and redirection.
Chunked assignments — long assignments and tests should be divided into smaller sections with brief breaks between sections to address sustained attention limitations.
Written instructions provided for multi-step tasks — to compensate for working memory weaknesses; Ethan should not be expected to retain more than two verbal instructions at a time without a written reference.
Graphic organizers for written assignments — to provide external organizational structure for writing tasks, addressing both his executive function weaknesses and his written expression disorder.
Reduced homework load — modified to focus on skill practice rather than volume; Ethan should be assigned approximately 50-75% of the standard homework quantity to prevent excessive time burden on the family.
Movement breaks — scheduled opportunities to stand, stretch, or perform a brief physical task every 20-25 minutes during seated academic work.
Organizational check-in — a brief daily check-in with the teacher or aide at the end of the school day to review the assignment notebook and ensure all materials needed for homework are in the backpack.

I am available to consult with the 504 team regarding implementation of these accommodations. Please feel free to contact me at (704) 555-0487.

Sincerely,

Dr. Karen L. Whitfield, Psy.D. Licensed Clinical Psychologist — NC #6192 NPI: 1357924680 Whitfield Neuropsychological Associates 5600 Monroe Road, Suite 220 Charlotte, NC 28212

This is a sample for educational purposes only — not real patient data.

How to Write It Step by Step

Step 1: Gather assessment data. Compile all relevant evaluation data, rating scale results, clinical observations, and academic records. If you are the treating clinician rather than the evaluator, coordinate with anyone who has conducted formal testing.

Step 2: Understand the school's process. Different school districts have different 504 procedures. Some accept outside evaluations and letters; others conduct their own evaluations. Ask the parent what the school has requested so your letter addresses the school's specific requirements.

Step 3: Describe functional limitations in educational terms. Translate clinical findings into classroom-observable behaviors. A teacher needs to know that "Ethan cannot sustain attention on independent work for more than 10 minutes," not that "the client meets DSM-5 criteria for ADHD-C." Use language that educators can understand and apply.

Step 4: Connect each accommodation to a specific limitation. The 504 team needs to understand why each accommodation is being recommended. Do not simply list accommodations without clinical justification. The connection between the limitation and the accommodation should be explicit.

Step 5: Be specific and practical. "Extended time" is vague — specify 1.5x or 2x. "Preferential seating" without specification is less helpful than "seating near the teacher and away from windows and high-traffic areas." The more specific your recommendations, the more likely they will be implemented effectively.

Step 6: Send the letter to the parent, not directly to the school. Unless you have explicit authorization to send the letter directly to the school, provide the letter to the parent and let them submit it as part of the 504 request. This preserves the parent's control over the disclosure of clinical information.

Common Mistakes

Writing a letter that diagnoses without describing functional impact. A letter that states "this child has ADHD" without describing how ADHD affects the child's functioning in the classroom provides the school with little actionable information. The diagnosis alone does not establish the need for accommodations — the functional impact does.

Recommending accommodations without clinical justification. If you recommend extended time without explaining the processing speed weakness or attention deficit that necessitates it, the school may question the recommendation. Every accommodation should be tied to a documented limitation.

Using clinical jargon. Teachers and administrators are not trained in clinical terminology. Replace "executive function deficits in the domain of cognitive flexibility" with "difficulty shifting between tasks or adapting when instructions change unexpectedly."

Recommending modifications instead of accommodations. There is a critical distinction: accommodations change how a student accesses the curriculum (extended time, preferential seating), while modifications change what the student is expected to learn (reduced curriculum, alternative assignments). Section 504 covers accommodations. If the student needs curriculum modifications, they may need an IEP under IDEA.

Omitting the student's strengths. A letter that describes only deficits does not give the 504 team a complete picture. Including the student's cognitive strengths, areas of academic competence, and positive behavioral attributes helps the team understand the student's full profile and design accommodations that leverage strengths.
